or here:

“…..willows form thickets which can cause floods and erode vulnerable banks, especially on flood plain areas.” (my emphasis)

Although some of us hold to the peculiar idea that climate extremes (especially high rainfall periods) have something to do with it, according to anti-willow literature, it is willows that cause flooding. Continue reading
